Boeing to restructure its defense and space unit

June 13 (Reuters) - Boeing Co said on Tuesday it would restructure its defense, space and security (BDS) division into smaller units and cut about 50 jobs this year, as the world's largest plane maker looks to make the business more agile.

The business, which accounted for nearly a third of the company's total revenue in 2016, will be divided into seven units, instead of five currently, effective July 1, with all reporting to BDS Chief Executive Leanne Caret.

Boeing's military aircraft business, part of the BDS unit, will be rearranged into three smaller segments: autonomous systems, strike surveillance and mobility, and vertical lift.

Autonomous systems, led by Chris Raymond, will comprise Boeing's subsidiaries Liquid Robotics, which makes the Wave Glider ocean surface robot, and Insitu unmanned aerial vehicles, among some other businesses.

The strike surveillance and mobility business, led by Shelley Lavender, will include the F-15 and F/A-18 fighters and P-8 maritime patrol aircraft.

Boeing's AH-6i, AH-64 Apache, and CH-47 Chinook helicopters will become part of the new vertical lift segment, led by David Koopersmith.

Boeing said its network and space systems business, also part of the BDS unit, will be reconstituted as space and missile systems. The business will be led by Jim Chilton.

The business makes satellites and other space and intelligence systems, and includes its joint venture operation with Lockheed Martin Corp - United Launch Alliance.

The development, global operations, and phantom works segments will largely remain unchanged within the BDS unit, the company said.

Boeing is aggressively building its services businesses to capture new revenue and lift profit margins from high single digits to mid-teens by 2020.

Chief Executive Dennis Muilenburg established a services business unit earlier this year that combines commercial aircraft and defense services.
